Abstract: Although it is widely recognised that a compatible approach is required in performing restoration works, a lack of knowledge still prevails concerning the choice of the parameters to take into account in the assessment of a sustainable level of compatibility of such actions.
The INCO-MED project PRODOMEA (Project on high compatibility technologies and systems for conservation and documentation of masonry works in archaeological sites in the Mediterranean area) has been expressly set up to produce a widely accessible system of information on conservation works carried out on masonry of archaeological sites located in the Mediterranean Basin. The final aim is to support future actions by suggesting methods and technologies of intervention that are compatible at different levels.
With this purpose, Roman archaeological sites were selected in Italy, Portugal, Jordan and Syria, in order to perform sampling and analysis of bedding and plastering mortars, both original and from restoration, aiming at assessing a correct compatibility approach.
The aim of the present work is to provide results obtained at one of the target sites, Villa Domizia on Giannutri Island (Italy). The characterization of the different types of mortars identified and the evaluation of the damage affecting the materials, alongside the identification of the natural and anthropogenic sources of deterioration, are presented.
The discussion of results will be performed in the framework of the compatibility approach developed within the PRODOMEA Project.
